Motors and Armatures 12193 Dual Run Capacitor 55/5 Mfd 370V

Product Description

The MOTORS AND ARMATURES 12193 is a dual run capacitor rated at 55/5 microfarads (MFD) and 370 volts AC, designed for use in single-phase residential and light commercial HVAC systems. Dual run capacitors serve two motor windings simultaneously, supporting both the compressor and the condenser fan motor from a single component. This round-style capacitor provides continuous duty operation and is a standard replacement part installed by licensed HVAC technicians during seasonal maintenance, compressor hard-start diagnostics, or capacitor failure calls.

This capacitor is suited for split-system air conditioners and heat pumps where a single dual-rated capacitor supplies the run capacitance for both the compressor motor and the outdoor fan motor. The 55 MFD section serves the compressor winding and the 5 MFD section serves the fan motor. The round form factor fits standard capacitor brackets found in most outdoor condensing units.

Key Features

• Dual run capacitor supporting compressor and fan motor from one unit
• 55/5 MFD rating covers both motor sections
• 370 VAC rating suitable for standard residential HVAC applications
• Round form factor fits common condenser unit capacitor mounting brackets
• Continuous duty rated for sustained operation in outdoor condensing units

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light commercial air conditioning and heat pump condensing units requiring a 55/5 MFD 370 VAC round capacitor.

Installation Notes

Dual run capacitors are serviced by licensed HVAC technicians. Disconnect and lock out all power to the condensing unit before handling any capacitor, as capacitors retain a dangerous charge even after power removal — discharge the capacitor safely using an insulated resistor or capacitor discharge tool before disconnecting leads. Verify MFD rating and voltage rating match the equipment nameplate before installation. Follow NEC and local electrical code requirements for outdoor disconnect and wiring practices.
